WATER-MOTO R.

SPECIFICATION forming part of Letters Patent No. 349,856, datedSeptember 28, 1886.

Application iiled May 12, 1886. Serial No. 201,935.

invention consists of a rotary water-wheel provided with buckets havinginclined ends and semicircular cup-shaped rear parts,which are supportedby the flanged rim of the wheel.

The invention consists, further, of an improved construction of thewater-injection nozzle and valve, as will appear more fully hereinafter,and nally be pointed out in the claims.

In the accompanying drawings, Figure l represents a side elevation of myimproved water-motor, parts being broken away to show injection-nozzlein section; and Fig. 2 is a vertical transverse section of thesupply-regulat- .ing valve on line x w, Fig. l.l

Similar letters of reference indicate corresponding parts.

A in the drawings represents the shell or casing of my improvedwater-motor, which casing is made of cylindrical shape and supported ona suitable bed-plate, A. The lower part of the casing A is provided atone end with a supply-channel, a, and at the other end with adischarge-channel, b. At the interior of the casing is arranged awater-wheel, B, the shaft B of which is supported in eccentric bearingsof the casing in such a manner that the wheel is closer to thesupply-opening and farther from the discharge-opening,where by anarrower space is provided near the point where the water is injected,and a wider space at the opposite side of the casing where the water isdropped from the buckets and conveyed to the dischargechannel b. Thesupply-port a communicates by a channel, a,with a cylindrical casing,C', that surrounds the supply-regulating valve C. The valve C isarranged in an inclined position nearly tangential to the lower part ofthe water-wheel (No model.)

and seated in a cylindrical shell, C2, provided 5o.

with openings or ports d, that communicate with the exterior casing, C.The valve C is also provided with radial arms I, having slots oropenings and enlarged T-shaped heads b', which latter open or close theports d of the shell C2, so as to regulate thereby the supply of waterto the interior of the valve. The valve C is provided with a hollowshank, d2, that is extended through a stuffing-box of the casing C tothe outside, and provided with a 6o handle by which thesupply-regulating valve C can be turned on its axis either by hand or bya suitable governor, so as to supply a greater or smaller quantity ofwater.

Through the hollow shank d2 of the regulat- 65 ing-valve C passes aneedle-valve, D, which extends by its tapering inner end into theinjection-nozzle D of the casing A. The shank of the needle-valve D ispivoted at its outer end to a fulcrumed lover, D2, that may be ad- 7ojusted to different positions by means of an arc shaped perforated guidepiece, f, and clamp-screwf, as shown in Fig. l of the drawings. Theupper end of the lever D2 may be connected,when the motor is used forworking 7 5 an organ-bellows, by a cord to the feeders of the bellowsand automatically operated by the same, so as to set the needle-valve.The shank of the needle-Valve passes also through a stuffing-box at theend of the hollow shank of the 8o supply-regulating valve, so as toprevent leakage of water. The inner end of the needlevalve E is madehollow and provided with openings or ports e, that communicate with anannular pressure-equalizing chamber, C3, located between the casing ofthe supply-regulating valve C and the injection-nozzle D, so that thewater is injected in two jets into the buckets of the water-wheel B, onejet being forced through the hollow nozzle of the needle- 9o valve andthe second exterior jet through the injection-nozzle D. This has theadvantage that the force of water on the buckets of the water-wheel canbe varied, as either the injection-nozzle D may be entirely closed bythe needle-valve and the motor run by the smaller jet supplied by theneedle-valve or the needle-valve may be drawn back and the motor workedby the combined jets of the injectionnozzle and needle-valve.

The Water-wheel is constructed with sheetlnetal buckets'g, that aresoldered or other- Wise attached to the ring -shaped parallel anges ofthe rim, each bucket being made of a straight part, g', and a curved orsemicircular rear part, g2, which serves as a cup to receive the waterand deflect the same and shed it when below the line of the jet thatdrives or propels the water-Wheel. The seniicircular part of one bucketrests on the straight part of the next bucket, as shown in the drawings,the buckets forming a simple and efficient Waterwheel, which readilysheds the water as the Wheel rotates, and which utilizes advantageouslythe full force ofthe water, as the buckets prevent the recoil of thewater, so as to break or weaken the jet.

Having thus describedrny invention, I claim as new and desire to secureby Letters Patentizing-chamber and injection-nozzle, a needle- `valvelocated in the regulating-valve and provided with a hollow slottednozzle, whereby an exterior and an interior jet are supplied to thewater-Wheel, substantially as set forth.

2. A Water-,Wheel having a rim 4formed of ring-shaped flanges andbuckets formed of straight and inclined front parts and semicircularrear parts projecting back of the plane of the front parts and restingupon the straightV Water so as not to interfere with the jet,substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
